Europe massively increased its combined military and other aid to Ukraine in May and June to around €11 billion ($12.69 billion), compared to €6.7 billion in the preceding two months, a leading German institute said on Thursday.

Of the total, the Kiel Institute for the World Economy (IfW) calculates that €4.3 billion went towards military aid and €6.7 billion towards financial and humanitarian support as Kiev fights a full-scale Russian invasion for the fifth year.

According to the institute’s Ukraine Support Tracker, the US did not provide any aid during this period. However, US-made weapons comprise the bulk of the European supplies to Ukraine.

“Europe continues to depend on the access to US weapons systems to sustain its military support for Ukraine,” said Federico Mellace, senior analyst at the Ukraine Support Tracker.

The European Union provided the bulk of the overall funds via the new Ukraine Support Loan. This €90 billion loan is intended to underpin the Ukrainian budget and defence spending in 2026 and 2027.

Germany contributed €700 million in military aid, according to the figures.

While the volume of military aid in the first half of 2026 almost hit the previous year’s level, financial and humanitarian support for Ukraine fell significantly. The average monthly payments in this area were 41% below the 2025 figure.

The IfW tracks military, financial and humanitarian aid, having commenced its survey on January 24, 2022, one month before the start of Russia’s attack.

The data covers more than 40 countries, including the 27 EU members, the US and Japan, and uses a wide range of sources that include government bodies and media reports.

Europe remains dependent on US for arms

Europe continues to lead the way in military support for Ukraine, but weapons from the US play a key role.

The IfW reports that the US share of European military aid has continued to rise – both in terms of purchases from defence companies and deliveries from US stocks.

Between January and June 2026, European donors purchased arms worth at least €3 billion from US defence contractors. This represents around 30% of European military aid provided through the defence industry, the institute notes.
